Business Central, offers several features to ensure seamless data management, one of which is the AutoIncrement property.
This feature is designed to automatically generate unique identifiers for records, thus simplifying data entry and management.
However, like any feature, it comes with its own set of advantages and disadvantages.
Cons of AutoIncrement
Non-Consecutive Numbers: If records are deleted or transactions fail, the sequence of numbers can be interrupted, leading to gaps in the numbering.
Meaning also, if several transactions are performed at the same time, they will each be assigned a different number. However, if one of these transactions is rolled back, the number that it was assigned is not reused.
Also, If you delete some records from a table, the numbers used for these records are not reused.
Temporary Tables Limitation: AutoIncrement does not work with temporary tables, which might be a limitation for certain applications where temporary data storage is required.
No AutoIncrement in Table Extensions: Developers cannot define an AutoIncrement field in a table extension, which limits the extensibility and customization options for extended tables.
Data Migration Challenges: Enabling AutoIncrement for a field with existing data can be problematic, especially if there are zero values in the field. This requires careful data handling during migration.
Inconsistency During Data Imports: When importing data into Business Central, ensuring that the imported records align with the AutoIncrement sequence can be challenging.
Alternative to it and use on Entry tables
Do you know about GetLastEntryIntFieldValue() procedure in Business Central?
Business Central includes Codeunit 703, known as “Find Record Management.” This codeunit offers several utility functions that assist in handling records, particularly in searching, filtering, and retrieving values. Below are some methods within this codeunit, accompanied by examples and use cases:
Method: GetLastEntryIntFieldValue
Purpose: To fetch the integer value from a specific field of the last record in a table.
This method is usually encapsulated on entry tables into procedure GetLastEntryNo():
Entries on many places use temporary records where AutoIncrement as said is not allowed and also gaps in Entry No. are usually not okay, of course there are more cons to AutoIncrement on Entry tables.
Now you can make your own GetLastEntryNo() on same way for your Entry tables! 🚀
Pros of AutoIncrement
Effortless Unique Identifier Creation: AutoIncrement automatically generates unique identifiers for new records, eliminating the need for manual entry.
Time-Saving: Since the identifiers are generated automatically, it speeds up the data entry process.
Minimal Configuration: AutoIncrement is easy to set up and requires minimal configuration, making it accessible even to users who may not have extensive technical knowledge.
While AutoIncrement in Business Central offers numerous benefits in terms of simplicity, automation, and data integrity, it also has its limitations. Understanding these pros and cons is essential for businesses to make informed decisions about when and how to use this feature effectively.
For straightforward applications requiring minimal manual intervention, AutoIncrement is okay. However, for scenarios demanding more control and flexibility over data entry and record management, alternative approaches might be necessary.

One important Con for me is missing here: Once your integer field has reached its maximum value, the table cannot be used anymore, as you cannot reset the value.
Number sequences, on the other hand, provide a “Restart” method.
Oh well yeah! Great point. Thanks Natalie! 😊
